Abstract

The method involves variably adjusting the magnitude of the disengagement force (F) depending on the torque transferred to the gear ratio to be disengaged and/or the rate of change of the torque. The torque is determined using the accelerator pedal position. An Independent claim is also included for an arrangement for controlling coupling element disengagement in a motor vehicle gearbox.
